  The 5-methyl cytosine (5meC) genomic methylation patterns play crucial roles in mammalian development and are altered in cancer. The enzymes that create, maintain and modify the DNA methylation patterns are the DNA methyltransferases (Dnmts) which are all encoded by essential genes. The de novo Dnmts -Dnmt3a and Dnmt3b- establish the DNA methylation patterns early in mammalian development by introducing DNA methylation marks where no previous methylation exists. These enzymes do not exhibit affinity for specific DNA sequences, thus their recruitment to specific DNA loci and their activities must be tightly regulated. In particular, Dnmt3a2 –one of the two protein isoforms produced by the Dnmt3a locus- is the most abundant DNA methyltransferase in mouse Embryonic Stem Cells. To identify Dnmt3a (and DNA methylation) regulators we have searched for Dnmt3a2 interacting proteins in m.. View More»
